Gattyana amondseni is a scale worm described from the Arctic and North Atlantic Oceans at depths down to about 700 m.
Gattyana amondseni is a short-bodied worm with 38 segments and 15 pairs of elytra, which bear a marginal fringe of papillae. The lateral antennae are positioned ventrally on the prostomium, directly beneath the median antenna. Notochaetae are about as thick and sometimes thinner than the neurochaetae.
